common/sfc_efx/base: replace PCI efsys macros with functions

efsys macros that manipulate PCI devices cannot be defined in
common sfc_efx DPDK driver since in DPDK build the bus drivers
that provide required functionality are built after common drivers.

Replace the macros with function callbacks to remove that build
dependency. Drivers now should pass the callbacks directly to
efx function instead of defining implementation in efsys.

common/sfc_efx/base: add function control window lookup API

Riverhead NIC may provide a locator of function control window
(EF100 resource locator).
The locator may be present in a Xilinx capabilities table which
itself is located by looking into extended PCI capabilities.

PCI capabilities are made possible to access by adding PCI config
space interface to efsys.

APIs are implemented to facilitate function control window lookup:
- API to find an extended PCI capability given a capability ID;
- API to read Xilinx PCI capability;
